Marine geology is a kind of geology that focuses on the study of the ocean floor and the processes that shape it. It is a sub-discipline of geology that studies the physical and chemical properties of the ocean floor, as well as the organisms that inhabit it. MARINE geologists use a variety of tools to study the ocean floor, including seismic surveys, core samples, and remote sensing. They also use their knowledge of oceanography, sedimentology, and geophysics to interpret the data they collect. MARINE geology is an important field of study for understanding the history of the Earth's oceans and the effects of climate change on the ocean environment.
